Subaru Impreza

Mk4 Impreza

Subaru's fourth-generation Impreza hatch and sedan received the option of an efficiency-enhancing continuously-variable transmission (CVT) with paddle-shifters to simulate six stepped ratios, replacing the outmoded four-speed auto of its predecessor.

Other efficiency measures included a redesigned 2.0-litre 'boxer' four-cylinder petrol engine with an identical 110kW/196Nm power and torque output to the outgoing model, idle-stop technology and improved aerodynamics.

The upshot was a claimed 22 per cent fuel saving for the CVT-equipped variants, down to a combined-cycle fuel consumption figure of 6.8 litres per 100 kilometres while six-speed manual variants consumed 7.1L/100km.

Efficiency gains, which placed the small Subaru ahead many of its rivals, did not come at the expense of the brand's trademark symmetrical all-wheel-drive layout making the improvements all the more impressive given the weight and friction penalties associated with such systems.

One of the main technology highlights is a new multi-function display, which on entry-level models provided the driver with fuel efficiency information including how many minutes of engine running time have been saved by the idle-stop system.

On up-spec L and S models, a premium unit enabled the driver to compare the fuel efficiency of each journey including how much fuel was saved by the use of idle-stop and unless the optional satellite navigation unit was installed, it also displayed the reversing camera image.

All variants came with climate control, cruise control, six-speaker CD sound system with iPod, Bluetooth and USB connectivity, a height-adjustable driver’s seat, height and reach steering wheel adjustment and two interior 12-volt power outlets.
